How cold is splash pad water?

Splash pad water sits in the 'refreshing' zone, which is 65-78°F most of the time. The exact temperature depends on three factors: ground temperature where the supply line runs (cooler in northern states, warmer in southern), time of day (morning runs cooler than afternoon as ambient warms), and whether the pad recirculates (recirculating systems hold water in an underground tank that warms several degrees by mid-afternoon). Compare that to swimming pools, which run 78-86°F, or bathtubs at 95-100°F. Splash pad water always feels noticeably cold, especially when it hits a kid's chest or back. That cold blast is exactly what makes splash pads great on a 95°F day. For babies and small toddlers, ease them in slowly with edge sprays before standing under bigger features. A few high-end resort pads heat their water in shoulder seasons, but municipal pads almost never do.
